That's how I got them from a USGS 'distribution partner'. Same for the ones 
below. They're all 24k maps.

Yeah, xv, display, gimp, gqview... Opens them fine (just takes a few minutes). 
These are the same files, in the same directory as the last time I had drg 
problems, though I've re-indexed the maps since then a few times.

I'm not sure what's happening. I compiled libgeotiff, libtiff, proj, in the 
correct order, according to README.1ST. I shall try to compile them again, as 
maybe I didn't do it right...
